A gentleman walked into a department store and asked the clerk for some fish food. The clerk answered that to properly serve him, and to give him the best fish food possible, he would need more information. The guys went home, and came back with the type, age, weight, and general temperament of the fish, bought his fish food and went home.. A few days later the gentleman came in looking for dog food. after the lecture, and after he'd gone home and rounded up all the information, he was able to buy his dog food and go home. The gentleman came back later the same day with a little box in his hand. He walked up to the clerk, presented the box, and asked him to stick his finger in the little hole in the top. He , the clerk, stuck in his finger, and jerked it out yelling, "OH YUCK, OH, THAT'S NASTY. THAT'S CRAP IN THAT BOX." The customer said, "You're right. I need to buy some toilet paper, and I really don't have time to make two trips."
